While phone and tablet chargers don’t use much power when not in use, old power tool chargers can be real energy hogs. Unplugging chargers that waste energy is a good step to save power.
Leaving your phone charger plugged in without a phone has its problems. There are money, energy, fire, and environmental issues. To avoid these, unplug chargers when not in use, get smart outlets to control them from afar, and choose good, branded chargers for safety. In our digital world, small changes in how we charge can help make our living space more sustainable and safe.
